Title: ViaGialla as harbinger for buildings
Assuming that a concentration of 550 ppm CO2 in the atmosphere must not be exceeded in order to limit global warming to max. 2-3 degrees, then this means, in relation to Switzerland, that the overall emission of CO2 of Swiss buildings must be reduced from the current 20 million tons to 2 million tons. The ViaGialla project demonstrates the way to a future where the 550 ppm CO2 limit is not exceeded; furthermore, in annual inspections the knowledge attained to date and the technologies are examined. These inspections assure transparency and help ViaGialla to more precisely define its path over the next five years.
